OpenAI releases GPT-5.4 with native computer use
GPT-5.4 (March 5, 2026) unified GPT-5.3-Codex's coding strengths with general reasoning and built-in computer use, scoring 75% on OSWorld-Verified — above the 72.4% human baseline — with a 1.05M-token context; mini and nano versions followed on March 17.
Key facts
- GPT-5.4 Thinking and GPT-5.4 Pro: March 5, 2026 in ChatGPT, API and Codex
- GPT-5.4 mini (also for free tier) and GPT-5.4 nano (API only): March 17, 2026
- OSWorld-Verified: 75% vs 47.3% for GPT-5.2 and 72.4% average human
- OpenAI: 33% fewer factual errors than GPT-5.2
- API: $2.50 input / $15 output per 1M tokens; cache read $0.25; input doubles to $5 above 272K tokens
- Context window 1,050,000 tokens; up to 128K output tokens
- Critics noted mini/nano API prices were about four times higher than GPT-5 equivalents
What happened
OpenAI released GPT-5.4 as a single model combining reasoning, coding and agentic workflows, including native computer use (reading screenshots, clicking, typing, navigating apps), and improved deep research.
Why it matters
First OpenAI mainline model to beat the human baseline on OSWorld-Verified, marking computer-use agents as a mainstream capability.
